Book Description

Rare kaon decay experiments underway or planned for the BNL AGS will yield new and independent determinations of V*[sub ts]V[sub td]. A measurement of B(K[sub L][sup 0][r-arrow][pi][sup 0][nu][bar[nu]]) allows a determination of the imaginary part of this quantity, which is the fundamental CP-violating parameter of the Standard Model, in a uniquely clean manner. Since the measurement of B(K[sup+][r-arrow][pi][sup+][nu][bar[nu]]) determines[vert-bar]V*[sub ts]V[sub td], a complete derivation of the unitarity triangle is facilitated. These results can be compared to high precision data expected to come from the B sector in a number of ways, allowing for unique tests of new physics.
